とするサーボ弁用フィルタ制御装置。3.4 In the flow connected to the actuator 2 of the servo valve 1, when the pressures in both flow paths 3 and 4 are approximately equal, there is a middle position where each of the two paths 3 and 4 are closed, and one of both flow paths 3 and 4. When the pressure is increased, a freely movable spool 5 is interposed between a switching position where the high pressure side flow path is opened and the low pressure side flow path is closed due to the high pressure, and the spool 56 is connected to the low pressure side closed at the switching position. The flow path is connected to a common 1 through which the spool 5 and the high pressure line filter 6 are interposed.
Each of the channels is characterized by communicating through the main bypass flow path 7.
